I am pretty new for ATL and model transformations. And i am trying to transform from XSD to XML and vice versa.

In order this to work, i needed the metamodels of these two model files. Then i discovered that EMF can generate .ecore from the XML Schema file. Well i have build the emf project and i also had tried to create a user model from that. However when i treid to use the .ecore files from the EMF projects on my ATL project i have found an error saying that the packages are not found.

I have tested by
1. coping the .ecore files and pasting in the ATL project
2. moving the .ecore to the ATL project
3. using the path of the EMF as the source of the metamodel direactly on the ATL file and during run configuration.
